This invention has for an object to produce a heel for shoes, which may be removed, renewed, or replaced at any time without having to resort to the services of a shoemaker. A further object is to produce a heel for shoes, which is interchangeable as to varying heights of heels worn for difierent occasions panying drawings, in which Fig. 1 is a side elevation showing a shoe equipped with a heel embodying my lnvention.

Fig. 2 is an inverted plan view of the shoe 1 shown in Fig. 1, showing the heel embodying my invention.

Fig. 3 is a perspective view of a plate forming a detail of my invention.

Fig. 4: is a perspective view showing a key which is employed to unlock the attaching latch of the shoe heel.

Fig. 5 is a side sectional elevation of my improved heel, taken on the line 5 5 of'F1g. 2, showing the key in place previous to unlocking the heel.

Fig. 6 is a view similar to Fig. 5, showing the key inserted and turned to release the heel latch.

The heel consists primarily of a base plate 7 which is secured to the sole continuation 8. To this is attached the removable portion of the heel, which consists of a body 9, either of wood, leather or other material, and a rubber tread 10 ofthe usual type. The metal plate 7 is shaped with a turned edge 11 which forms a peripheral groove 12. In the center of the plate is a notched dovetail bar 13 which has raised ends 14. and 15 with a depressed or notched part 16. The end 15 has a groove 17 through which key 18 is passed in unlocking the heel, it is readily seen that this procedure may be reversed, since it may be necessary to turn the groove portion 17 about, so the key portion notched part 16, through a groove or key hole may be made in the back of the heel portion of the plate 7 to operate the key in this manner, this is so obvious that it was thought unnecessary to complicate the drawing therefor. The body 9 of the heel is grooved and rounded entirely around the side and bottom portion of the heel so as to enable it to pass into and to receive the extended upper portions of the plate 7, with a central dovetail grooveto permit it to pass over the bar 13. The body 9 is provided with a lock 19 which has a mounting frame 20 secured to the body 9. A latch or keeper 21 is mounted for reciprocation in the frame 20 under the action of a spring 22, so that, when the heel is pushed into the portions shown, the

latch drops into the notched part 16 of the bar 13, thereby locking the heel rigidly. The beveled edges of the latch 21 permit the beveled flatend 23 of the key to be forced beneath the latch, so that, when the key is rotated, the latch will be lifted above dovetail end 15 to permit the heel to he slipped ofi'. Advantages attained by this detachable heel structure are the ease with which various styles andheights of heels may be supplied a shoes base plate of the structure described. The ease with which the repair of a heel may be accomplished, either by renewing its entire heel structure or merely its rubber tread por tion 10, all without having to resort to a shoemaker in order to accomplish this. Shoe measurements are well known, as are the varying sizes to fit the .diiferent feet; this necessitates different sizes of heels and plates in my invention for the varying sizes of shoes. It is only necessary to know the number of the shoe, to secure the same number of heel which heel having been made universal to fit its particular plate makes the task easy for renewing, replacing or removing the heel for the novice.

Having thus described my invention what I claim is In a detachable heel structure for shoes comprising abase plate, the upper part thereof forming a peripheral groove and said Hit base plate being secured to the sole continuation of the shoe, a dove tail notched bar centrally located upon the base plate, having a groove in one of the raised ends adapted to receive a key, a heel portion grooved on its outside to pass into the peripheral groove of the base plate, and a dove tail groove in the heel bottom for passage over the dove tail notched bar, a lock in the heel bottom, and a spring actuated keeper mounting the lock, whereby the grooved heel portion when pushed into the peripheral groove portion of the base plate allows the keeper to drop into the notch of the dove tail bar, thereby locking the heel rigidly onto the base plate and whereby when a key is inserted the portions may be unlocked.

In Witness whereof, I aflix m signature.
